Report No. EdOQR000"01 dated November 7, 1985 and PSE&G Generic Qualifi-cation Report EESS No. M047-PNL-003 dated November 27, 1985. The inspector reviewed these documents and determined that they adequately address the NRC issue This item is close (Closed) IE Circular 79-CI-02 - Failure of 120V Vital Ac power Supplies No written response to this circular was required from the license The licensee's review of this circular against the four points recommended by NRC was documented in their internal letter dated August 8,1980 ( A. Christiana to E. N. Schwalje). The inspector reviewed this letter and determined that it adequately addressed the NRC issue This item is considered close (Closed) IE Circular 77-CI-16 - Emergency Diesel Generator Electrical Trip Lockout Features This item relates to an event that occurred at another plant in which a diesel generator output circuit breaker tripped open during a test while in the emergency made from a cause other than those permitted by the technical specification The Hope Creek diesel generator trips and start permissive functions conform to the requirements of Hope Creek technical specifications sectior 4.8.1.1.2.H.7. Verification of the trips and start permissives were confirmed during the pre-operational test phase by procedures PTP-KJ-1, 2, 3, 4 and will be periodically reconfirmed during the operational phases by test procedures OP-ST.KJ-001 thru 1 The licensee's emergency diesel generator trip lock-out features bypass any signal from negating a start or trip during emergency operation except for the signals which are vital and necessary for keeping the diesel generator running. These signals are engine overspeed and les lobe oil pressure which will shutdown the engine and overcurrent or excessive differential current which will trip the generator output circuit breaker ope This item is close (Closed) 79-80-23 - Potential Failure of the Emergency Diesel Generators Exciter Field Transformer During a full load test of emergency diesel generators by Florida Power and Light Company at their Turkey Point facility, overheating of the exciter power transformers occurred due to a design error. The diesel generators were General Motors (Electromotive Division) Model EMD-999-20 equipped with Model A-20 EMD generator which utilized a GE-single phase model 9T24Y1004 exciter power transforme .
The manufacturer determined that the problem was caused by high circulat-ing harmonic currents in the exciter transformer due to the neutral of the power generator and the neutral of the primary windings of the exciter transformer being connected. The manufacturer concluded that such connection was of no significant benefit and could lead to destruction of the transformer as a consequence of overheating. The manufacturer recommended that the neutral circuits be disconnected and the transformer primary neutral allowed to floa IE Bulletin 79-23 directed that all licensee's determine if they had like problems with their emergency diesel generator exciter The inspectors confirmed the licensee evaluation that the circulating harmonic currents in the exciter power transformer windings cannot occur at Hope Creek Generating Station because of major design differences. The generator and exciter are from a different manufacturer and the design does not include a similar exciter power transforme The emergency diesel generator is manufactured by Colt Industries; the generator is supplied by Beloit Power Systems division of Louis Allis Corporation and it is equipped with a Basler static excite Further the emergency diesel generators have been full load tested for 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> and overload tested for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> during preoperational test PTP-BB-3 without incidence of exciter overheatin Tnis item is close (Closed)_ IE Bulletin 79-01 - Environmental Qualification of Class IE Safety Related Electrical Equipment The inspector reviewed Bulletin 79-01 and supplements thereto including licensee actions required.

New tests were conducted on 12 transmitters in an environment simulating actual plant conditions. The test results indicated that all transmitters functioned satisfactoril The licensee concluded that the previous tests (in which they identified the drift problem) were not appropriately performed. On July 2, 1985 the licensee sent a letter to NRC withdrawing the deficiency repor The inspector reviewed pertinent documents on this subjec This item is close (Closed) Construction Deficiency item No. 85-00-11 - Inadequate Power to

Class 1E fobar Instrumentation Transmitters That Provide Plant Safety Signals to the Bailey Instrumentation Cabinets Initial calibration of these instruments revealed that the overall circuit loop impedance was too high to provide sufficient voltage to the Tobar transmitters to provide the design full range signal current to the follower instrumentatio A design change was made to bypass a 150 ohm current limiting resistor in each of these circuits and to install a current limiting fuse to serve the same function. This change increased the voltage across the Tobar transmitters and provided for proper calibration and operation to meet design criteri .
The inspector reviewed the deficiency, the design change, and impact of the change on the qualification of the instrumentatio Installation calibration and acceptance is complete for 14 channels with the remainder of the channels to be completed prior to fuel loadin No deficiencies were identifie This item is close (Closed) Violation 85-03-01 - Uncapped Instruments Tubing In Inspection Report No. 50-354/85-51, numerous uncapped instrument cali-bration connections on the GE transmitter racks were identified. A complete list of these uncapped connections was tabulated by the licensee in the SOR No. 2C-0053 dated November 8, 1985. The capping of these connections was completed on November 30, 1985 and documented in the resolution of SDR No. 2C-005 The inspector selected 12 instruments in GE Panels H21-P005 and P006 in the Reactor Building, elevation 77' and verified by direct observation that their calibration connections were properly cappe This item is close (Closed) Unresolve_d Item 85-61-07 - Plant _ Operating Procedures for Monitoring Snowfall and Snow Removal to Preclude Obstruction of the Emercency Diesel Generators Exhaust Systems The inspector reviewed licensee plant operating procedure Op-AB.22-139(G)
entitled " Acts of Nature" which was approved and implemented September 9, 198 Paragraph 4.8 of this procedure requires that if the snowfall is greater than 12 inches, the snow accumulation in the area of the diesel generator exhaust pipes shall be monitored each hour. It requires shovel-ing to remove snow in the vicinity of the exhaust pipes when snow accumu-lation reaches 36-inches. After snowfall has subsided, it requires periodic recheck for drif ting snow around the exhaust pipes. The inspector determined that the licensee procedure adequately addresses this issu This item is close (Closed] Unresolved Item 85-24-01 Fire Hazard Analysis~
(FHA) Not Properly Performed on a Fire Area Concept Basis
_
The licensee satisfied the commitment to revise the FHA to include a clear definition of all fire area The revised FHA contains in table 9A a description of each fire area and all rooms within each. A list of all

I safe shutdown equipment and the effects on safe shutdown from a fire or fire suppressants is also included in the analysis for each fire area. A random check on this analysis did not identify any unacceptable condi-tion This item is close (Closed) Unresolved Item 85-24-04 - Incomplete Spurious Signal Analysis The spurious signal analysis has been completed by the licensee. This analysis was performed using the majority / minority systems concept for each fire area. This concept examines the possiblity and effects of spurious signals in the minority system within the fire are For example if in a given fire area there are systems from both divisions I and II and if the majority of the equipment, cables and conduits are of division I then the minority system / division for that area is division I The spurious signal analysis examines the effects of the fire and fire suppressants for the division II systems involved in this area since it is systems from division II likely to be used for safe shutdown, because, division II by definition, is least affected by a fire in this area. A random review by the inspector, of areas analyzed did not identify any unacceptable condition This item is close (Closed) Unresolved Item 85-24-05 - Fixed Fire Suppression for the Control Console Pit in the Main Control Room The licensee added a Halon suppression system in the control room console pit to allay the NRC concern about the lack of fixed fire suppression in this area. The inspector walked down this system and determined that it is acceptabl The review of the system included a visual examination of the piping, discharge nozzles and piping supports. The inspector also reviewed the test data and test results for the agent (Halon) concentration and duration of concentration. This system has also been reviewed and accepted by NR No unacceptable conditions were identifie This item is close (Closed) Unresolved Item 85-24-06 - Fire Resistance of Metal Security Panels in the Main Control Room The inspector reviewed the documentation submitted by the licensee that substantiate the fire resistance of the metal security panel The construction of these panels is similar to the construction of fire rated door This configuration has been reviewed and accepted by NR This item is resolve .
(Closed) Unresolved Item 85-24-07 - Cable Penetration Seals The concern that a fire initiated failure of the cable trays and supports will cause a failure of the penetration seals in the fire barriers was addressed by the licensee. By letter dated August 27,1985 (R. Mittle to W. Buttler) the licensee provided the results of a structural analysis on cable tray supports. This analysis was based on a worst case fire scenario. NRR has reviewed this analysis, and concluded that because of the conservative assumptions made in conjunction with this analysis, the early response of the fire brigade and the presence of automatic suppres-sion in most fire areas, this concern has been adequately resolve (Closed) Unresolved Item 85-24-10 Incomplete Sprinkler Systems The inspector reviewed the modifications implemented by the licensee to complete the sprinkler systems identified in the above referenced unresolved item. No unacceptable conditions were identifie The inspector also reviewed an audit report on the status of fire suppression system performed by an independent consultant. This audit was performed to assess the fire protection system conformance with the applicable NFPA standards and also evaluate the adequacy of the fire protection systems. The inspector's review included the responses planned by the licensee, addressing the audit findin No unacceptable conditions were identifie This item is close (Closed) Unresolved Item 85-24-11 - Fire Detection System Audit The NRC concerns for the Hope Creek fire detection system capability were: (a) some detection systems Lay not meet the NFPA requirement (b)
detection in some areas is marginal and therefore additional detectors are required and (c) the FSAR should include a list of all safety related areas that lack detection and the appropriate technical justification for this lack of detectio The licensee responded to item (a) above by performing an audit of the fire detection systems. This audit was performed by an independent consultant. The inspector reviewed this audit and also the responses to the audit findings planned by the licensee, and did not identify any unacceptable condition The licensee provided additional fire detectors in areas where detection capability was marginal thus satisfying the NRC concern identified in item
